Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.
This includes ports
- with USE_GCC=yes or USE_GCC=any,
- with USES=fortran,
- using Mk/bsd.octave.mk which in turn features USES=fortran, and
- with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

Bump PORTREVISION for ports depending on the canonical version of GCC
in the ports tree (via Mk/bsd.default-versions.mk and lang/gcc) which
has now moved from GCC 6 to GCC 7 by default.
This includes ports
- featuring USE_GCC=yes or USE_GCC=any,
- featuring USES=fortran,
- using Mk/bsd.octave.mk which in turn features USES=fortran, and those
- with USES=compiler specifying one of openmp, nestedfct, c11, c++0x,
c++11-lib, c++11-lang, c++14-lang, c++17-lang, or gcc-c++11-lib.

Bump PORTREVISIONs for ports depending on the canonical version of GCC and

Bump PORTREVISIONS for ports depending on the canonical version of GCC and
lang/gcc which have moved from GCC 4.8.5 to GCC 4.9.4 (at least under some
circumstances such as versions of FreeBSD or platforms).
In particular that is ports with USE_GCC=yes, USE_GCC=any, or one of
gcc-c++11-lib, openmp, nestedfct, c++11-lib as well as c++14-lang,
c++11-lang, c++0x, c11 requested via USES=compiler.

Back out parts of the r366375 that had nothing to do with staging or fixing
the build on -CURRENT. This restores Makefile sanity and diff clarity with
r357486. (Fixing the build without GCC would be attempted separately.)

Support LIBS like LDFLAGS.
- Add LIBS="${LIBS}" to MAKE_ENV and CONFIGURE_ENV.
- Add an option helper for LIBS.
- Adjust all ports that already use LIBS. Also remove references to
PTHREAD_CFLAGS and PTHREAD_LIBS while here.
- Some ports did not support having a LIBS environment variable and
required additional patches.
Somewhat simplified a linker command line looks like:
${CC} ${src_LDFLAGS} ${LDFLAGS} ${src_LIBS} ${LIBS}
where src_LDFLAGS and src_LIBS are controlled by upstream and LDFLAGS and
LIBS can be controlled by us. If possible -L and -l flags need to be

Convert all :U to :tu and :L to :tl
Since FreeBSD 8.4 and FreeBSD 9.1 make(1) do support :tu and :tl as a
replacement for :U and :L (which has been marked as deprecated)
bmake which is the default on FreeBSD 10+ only support by default
:tu/:tl a hack has been added at the time to support :U and :L to ease
migration. This hack is now not necessary anymore
Note that this makes the ports tree incompatible with make(1) from
FreeBSD 8.3 or earlier
